I'm about 6 months in with my CPAP, from about 3 weeks in to 6 weeks in I'd sometimes wake up having removed mask, but it's not happened for a good few months.
My sleep specialist recommended using washing up liquid & water on the mask daily & soaking both mask & hose in warm water once a week.
Previously I'd been washing mask daily in foaming face wash, I noticed a big improvement since switching to washing up liquid.
I'd add I work as a travelling sales rep, different hotels 3/4 nights a week so do follow daily washing mask routine. I have a dish brush with built in washing liquid container, it's very quick and easy to use.
